The objective of this project was to develop a simple test to design bituminous concrete mixtures for fatigue resistance. Included are two literature reviews: (1) current fatigue testing procedures, and (2) simple test methods that offer possibilities for fatigue prediction.

Transport bituminous mixtures using motor trucks with tight metal or metal lined dump bodies. For hot mixes on unusually long hauls or for work after

CHAPTER 7 TESTING OF ASPHALT CONCRETE MIXTURES Asphalt Testing This section will deal with the methods of determining asphalt concrete properties by laboratory testing. In a hot-mix asphalt (HMA) paving mixture, asphalt and aggregate are blended together in precise proportions. The relative proportions of these materials

reduction in design asphalt content if incorporated in the mixture design process. Laboratory tests indicate that warm mix asphalt is initially less stiff than hot mix but stiffens considerably during the first year of service and with increases in laboratory oven curing time/temperature. Field …

The Bituminous Mixtures Laboratory contains the following equipment: SUPERPAVE Gyratory Compactor (SGC): Simulates the kneading action of rollers used to compact asphalt concrete pavements by applying a vertical load to an asphalt mixture while gyrating a mold tilted at a specified angle. SGC is the new equipment used in volumetric pavement design.

Tex-205-F, Laboratory Method of Mixing Bituminous Mixtures Overview Effective date: August 1999 to October 2004 This method is a procedure for combining various sizes of aggregates and blending them with asphalt to obtain uniform bituminous mixtures. Apparatus The following apparatus is required: ♦ a balance readable to 0.1 g accurate to 0.5 g

LABORATORY METHOD OF MIXING BITUMINOUS MIXTURES TXDOT DESIGNATION: TEX-205-F CONSTRUCTION DIVISION 4 – 4 EFFECTIVE DATE: AUGUST 2016 4.17 Split the mixture into the appropriate size, as need it, and place the samples in the oven. 4.18 Identify each mixture with a laboratory number and indicate the percentage of asphalt.

Realistic laboratory curing of bituminous mixtures 7 Except for the B55/70 straight-run bitumen, the RTFOT ageing rate has not been reached after mixing or immediate Marshall compaction. On the other hand, reheated bituminous mixtures or stabilised bituminous asphalt behaviour are quite similar.

Before asphalt mixtures with HP binder were used on a jointed concrete overlay project, a trial project to evaluate the constructability and laboratory performance of a mixture using this type of binder was conducted. The trial project compared an asphalt surface mixture with an HP

content of bituminous mixtures using the NCAT Asphalt Content Oven. The results were documented and a test procedure was written which incorporated the studies fmdings. The results of this study demonstrate that the NCA T Asphalt Content Oven can be used to measure AC contents accurately.

A bituminous mixture designated as GB3 (GB stands for "Grave Bitume" in French) was used in the RRT. This mixture is commonly used for base course construction in France. The GB3 bituminous mixture was produced in the laboratory in accordance with the EN 12697-35 Standard.
